MetaLeach Limited is a wholly owned subsidiary of AIM quoted Alexander Mining plc. MetaLeach was formed to enable the commercialisation of its proprietary hydrometallurgical mineral processing technologies. These technologies have the potential to revolutionise the extraction processes for many base metals deposits by reducing costs, and hence enhancing operating margins, at the mine site. In addition, many deposits that hitherto have not had viable processing options may be treatable.

MetaLeach owns the intellectual property to hydrometallurgical technologies, of which AmmLeach® (patents granted and pending) is the most important. AmmLeach®is an environmentally friendly, cost effective processes for the extraction of base metals from amenable ore deposits under ambient conditios, allowing the production of high value products at the mine site (i.e. metal powder or sheets). These technologies were created as a result of the Company’s work at its former copper oxide project in Argentina and subsequent research and development.

The following metals are targets for the AmmLeach® process:

Copper oxide deposits

Copper/Cobalt oxide deposits

Zinc oxides deposits

Gold/Copper oxides and Silver/Zinc oxides (alkali leaching);

A significant number of confidentiality and testwork agreements have been signed with multinational mining groups, as well as intermediate and junior companies.
